By ED BARK@unclebarkycomCBS’ Season 8 finale of How I Met Your Mother outdrew NBC’s competing The Voice Monday night by at last revealing -- the mother.

No need to spoil it yet, save to say the designated actress likely won’t ring a bell with at least 99 out of 100 viewers. But whatever the case, HIMYM lured 275,368 D-FW viewers from 7 to 7:30 p.m. in outpointing the first half hours of both The Voice (254,715) and ABC’s Dancing with the Stars (240,947). CBS won that slot by a much wider margin among advertiser-prized 18-to-49-year-olds.

The Voice then ran first from 7:30 to 9 p.m. in both ratings measurements. And at 9 p.m., ABC’s season finale of Castle easily clasped both golds. On Fox Sports Southwest, the Texas Rangers’ late-starting road loss at Oakland averaged 137,684 total viewers.

In Monday’s local news derby results, the 13th weekday of the May “sweeps” turned out to be a big one for WFAA8. The station swept the 5, 6 and 10 p.m. Nielsens in both total viewers and 25-to-54-year-olds, the main advertiser target audience for news programming.
